Re: Integrate another project on GWT

Well, I think I fixed it. I've read this in the troubleshooting area:

" java.security.AccessControlException: access denied
The problem occurs if you mistakenly enabled the Google App Engine
feature for your project when you created the project, or at a later
time during development, and have server-side libraries or classes
packaged with your GWT application war folder that violate the Java
App Engine sandbox."

It's not the same error that I got, but it seems that what my Lucene
files are doing is just this, violating the App Engine... I dont have
my files in the war folder, but it doesn't say that the way of
resolving it is moving any file into the server package, only
disabling the App Engine...

What do u think about that??
